Serial No. 227,216.

This invention refers to the spinning tubes which carry the spinning bobbin 1n flyer spinning and like frames, which tubes are mounted and revolved upon dead spindles, and has for its object the improved working and lubricating of such spinning tubes.

. According to this invention, groups of spinning tubes which carry the spinning bobbins in flyer spinning and like frames which tubes are mounted and revolve on dead spindles, are lubricated by means of a supply of oil which when lubrication is required, is raised to such a level as will cause the oil to flow into and lubricate the said tubes. In one case the oil container is placed below the level of the oil tubes. The oil tubes and containers are inverted when lubrication is required and the oil flows into the spinning tube. In another case the oil supply is carried at the same level as the spinning tube. The spinning tube is carried on one limb of I a U shaped dead spindle which is tubular throughout. The group of U shaped dead spindles referred to is tilted when lubrication is required so that the oil will overflow at the top of the limb on which the spinning tube revolves and will thus pass into the spinning tube. V

Figure 1, is a vertical section through a bobbin and tube constructed in accordance with the invention, and

Fig. 2, is a similar section illustrating another form of the invention.

Fig. 3 is a partial plan view of the embodiment illustrated in Fig. 1, and

Fig. 4 is a partial elevation of the embodimppt illustrated in Fig. 1 as seen from the le In giving a practical example of our in vention as applied to a worsted spinning frame having the flyers mounted and driven on the bottom side of the top rail and the studs and tubes mounted on the same vertical line of axis as the flyer on the lifter rail, we employ Figure 1, a top rail 1 with aflyer 2 mounted and driven in the usual way on the under side of the said rail 1. At a suitable distance below the fiyers 2 .we mount a lifter rail 3 which is traversed up and down in a usual manner. On the lifter rail 3 we bore resting on the bottom of the cup a hole central to the axis of the flyer 2. In a hole in the lifter rail we mount a spindle socket 4: having on its upper side a cup 4:

and bound on the lifter railby a cup nut 5.

The cup nut'5 acts also as an oil container as hereafter described. We mount firmly in thespindle socket 4 a dead spindle 6 extending upwards to a suitable distance and on it we mount a bobbin tube 7. The cup 41. of the spindle socket 4 extends upwards to a suitable distance and has placed on it a cover 8. On the top of thecover 8 a spinning bobbin 9 which is mounted upon the bobbin tube 7 rests. The bobbin tube 7 restsupon a thimble 10 fixed on the dead spindle 6 and 4 of the spindle socket 4. At the lower end of the bobbin tube 7 we mount clear of the cover 8 of thespindle socket cup P an inverted oil cup 7 The dead spindle '6 extends to the lower end of the spindle socket 4 and has formed on its side an oil groove 6 extending upwards into the bobbin tube 7. The cup nut 5 of the spindle socket 4 is made with an oil cup 5 at its lower end. This oil cup 5 is of suflicient depth to hold a supply of oil.

At a suitable distance above the bottom of the dead spindle 6 into the bobbin tube 7 and lubricates same. On being re-inverted any surplus oil flows back to the oil cup 5 of the cup nut 5. In other words the oil container is adapted to cause oil to flow into the spinning tube when the lifter rail is turned about the horizontal axis of the trunnions.

In giving a second example of our invention also as applied to a worsted spinning frame we employ a top rail a flyer and a .lifter rail all as in the foregoing first example. On the upper side of the lifter rail 3 we mount a stool 11 and in it a U shaped tubular dead spindle 12, the front limb 12 of which is coaxial with the flyer 2 and has mounted on it a bobbin tube 13 carrying a spinning bobbin 14. The back limb 12 of the U shaped dead spindle 12 is filled with oil which passes up into the front limb 12 5 the two limbs rising to the same height. The

lifter rail 8 in this form of the invention may also be invertibly, or tiltably mounted, as in the first example described, in any known or convenient manner. It may then be tilted m forward to raise the back limbs 12 of a group of dead spindles 12 and lower the front limbs 12 so that the oil will overflow into the bobbin tubes and lubricate them.

Vith the understanding that the examples 15 described and illustrations given are presented, not to limit the invention, but merely to indicate how the invention may be applied,

We claim: 1. Apparatus for lubricating fiver spin- ()0 nine; and like frames, comprising a tube for carrying a spinning" bobbin, an oil container extending below said tube. and an invertibly mounted lifter rail carrying said tube and said oil container, said oil container being adapted to cause oil to flow into the spinning tube when said lifter rail is turned about a horizontal axis.

2. Apparatus for lubricating flyer spinning and like frames, comprising a tube for carrying the spinning bobbin, an oil container consisting of a U-shaped tubular dead spindle extending below said tube, and an invertibly mounted lifter rail carrying said tube and said oil container, said oil container being adapted to cause oil to flow into the spinning tube when said lifter rail is turned about a horizontal axis.

In testimony whereof we have signed our names to this specification. 4Q THOMAS ALE ANDER- BOYD.
